Summary: The study showed that both VDBD and DCSBD plasma sources had similar effects on improving the surface of BOPP film, but VDBD treatment resulted in slightly higher surface roughness and more efficient adhesion. Comparable results were achieved for both plasma sources in terms of enhanced surface wettability, degree of oxidation, and stability of induced changes, with DCSBD having less impact on surface deterioration than VDBD.

Summary: Nanotopographic surfaces have been proven to effectively kill bacterial cells upon contact, providing an alternative method to fight against bacterial colonization and resistance. This study investigates how fluid flow affects bacterial cell adherence on nanotopographic surfaces, revealing that increasing flow rates significantly reduce the number of live cells, while increasing the number of dead cells adhering to the surface.

Summary: This study investigated the drying method of bacterial nanocellulose (BC) and the subsequent argon plasma modification to improve cell adhesion. After argon plasma modification, the BC-L samples had higher porosity and better cell growth, while BC-AD samples showed improved initial cell adhesion and colonization after PM, forming continuous cell layers. This work suggests that surface modification of BC has great potential for skin tissue engineering and wound healing.

Summary: Polypropylene (PP) tape by tape fabric was modified with atmospheric pressure non-thermal plasma (APNTP) to enhance hydrophilicity and adhesion. However, the ageing of the modified surface over time is a major drawback of plasma surface modification. This study investigates the effect of atmospheric plasma treatment on the adhesion properties of plasma-treated and polyurethane (PU) coated fabric in terms of ageing behavior up to 4 weeks.

Summary: Membrane bioreactors (MBRs) face high costs due to biofouling, which is caused by the binding of adhesins on microbial appendages to the surface. Two compounds, dodecyl-8-D-maltoside (DDM) and methyl alpha-D-mannopyranoside (Me alpha Man), were investigated as potential biofilm mitigation tools. DDM prevented biofilm formation in microplate experiments, while Me alpha Man increased biofilm. In a biofilm reactor setting, DDM prevented detectable wastewater culture biofilm formation on different membrane materials. The mechanism of anti-adhesion involved the binding of DDM to polar amino acids on microbial appendages.

Summary: This study investigates the effects of hygrothermal ageing and atmospheric plasma surface treatment on a 3D carbon/epoxy-amine woven composite material. The results show that hygrothermal ageing leads to irreversible absorption behavior and modifies the surface chemistry and topology, while atmospheric plasma treatment causes oxidation of the matrix but also removes the adsorbed humidity.

Summary: This study investigates the shear characteristics of the concrete-silty clay interface under concrete surface roughness, normal stress, and moisture content using modern friction theory. An adhesion-ploughing friction model is established to predict the shear strength of the interface. The results show that the shear strength of the interface is positively correlated with normal stress and concrete surface roughness, while negatively correlated with moisture content.

Summary: A hybrid computational framework was developed to predict the density of plasma generated species in plasma jets. The study found that the choice of turbulence flow models has a significant impact on the densities of certain species, with the detailed LES model being more suitable for Ar jets. However, the majority of species densities are not severely affected by the different turbulence flow models.

Summary: In this study, the controlled release of the widely used herbicide MCPA was achieved using high surface-area metal-organic frameworks (MOFs) and biodegradable polymer composites. The best performance for MCPA release was observed with the postsynthetically loaded MOFs, and enhanced release was observed when the MOFs were incorporated in polycaprolactone (PCL). These composite materials show promise for future agricultural applications.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
